Berserk: Guts gets nuked, anyone stronger, faster, and/or more haxxed than him stomps
Metal Gear: only beating Old Snake and/or The End by waiting for them to succumb of old age. Most of the cast is too knowledgeable on the military and too skilled in all things combat and warfare to be effectively countered, to say nothing of how physcially OP they are compared to any IRL human. And if a Metal Gear or cyborg from MGS4 onward shows up, forget it, total stomp.
Lord of the Rings: basically has to resort to nukes to take out the strongest humans, elves, dragons, etc. Gets rekt by the Nazgûl and any of the Maiar or Valar.
Devil May Cry: the US Military was canonically stomped by Tier 9 and Tier 8 fodder demons. Helpless against this verse.
One Punch Man: does pretty good against most Heroes in Classes C - A, and monsters in Level Wolf - Demon. Most, not all, and those remainders by themselves are entirely sufficient to take out the military. Gets stomped by Dragon Level monsters and S Class Heroes.
Demon's Souls: Easily kills fodder and low tiers, struggles to varying degrees against mid and high tiers. God tiers are capable of too much swift and widespread destruction to be countered, with the absolute strongest characters just erasing the Earth itself.
Dark Souls: US Military clears the roster up to and including the giant lava monster with the funny name. Everything past that obliterates the US Military easily, and at very least takes out much of America itself in the process. Wouldn't be surprising if Gwyn and Lords of Cinder are immune to nuke hax too since they basically merged their souls with the sun.
Bloodborne: even regular beasts are heavily resistant to regular small arms fire, and many of the early game bosses could feasibly shred tanks, so the US Military loses much of its ground forces before blowing apart the early and mid game threats with air and naval bombardment. After that, they go insane and drop dead of madness trying to fight the Great Ones or their Kin, which I could also see being pretty tolerant of radiation.
Elden Ring: does alright against the early game, but is pretty helpless against the sheer power and hax of mid game bosses and onward, such as Radahn.
Evil Dead: Canonically struggled against Deadites, but could take them out if able to figure out what they're dealing with. Could take out Ruby if they hit her with something strong enough to damage her past her regen threshold. The military is pretty screwed against Baal, the Kandarian Demon, or Kandar the Destroyer though, the latter two they were canonically useless against.
